Constraint Propagation
The domain expressions define a directed graph on the variables. In the current version of the system, the constraint graph must be a acyclic, which means that information flows in…

Local Search Algorithms and Optimization Problem
The informed and uninformed search expands the nodes systematically in two ways: keeping different paths in the memory and selecting the best suitable path, Which leads to a solution state…

Depth First Search
Depth-first search (DFS) is an algorithm for traversing or searching tree or graph data structures. The algorithm starts at the root node (selecting some arbitrary node as the root node…

Types of search algorithms
There are far too many powerful search algorithms out there to fit in a single article. Instead, this article will discuss six of the fundamental search algorithms, divided into two categories, as shown below.…

What is AI?
A machine with the ability to perform cognitive functions such as perceiving, learning, reasoning and solve problems are deemed to hold an artificial intelligence. Artificial intelligence exists when a machine…

Mirror mirror on the wall, which is the shortest path of them all?
In order to determine which of these six possible paths is the shortest one — and thus the ideal choice for our salesman — we need to build up the cost of every single…

Brute-force to begin with
The traveling salesman in our example problem has it pretty lucky — he only has to travel between four cities. For simplicity’s sake, we’ll call these four cities w, x, y, and z. Because we know…

The Trials And Tribulations Of The Traveling Salesman
Aswe dive deeper and deeper into the world of computer science, one thing starts to become very clear, very quickly: some problems seem to show up again and again, in…
